In the past fifteen years there has been considerable interest in neural circuits that initiate behavior patterns. For many types of behaviors, this involves decision-making circuits whose primary elements are neither purely sensory nor motor, but represent a higher order of neural pro cessing. Of the large number of studies on such systems, analyses of startle circuits compose a major portion, and have been carried out on systems found throughout the animal kingdom. Startle has been an im portant model because of the reliability of the behavioral act for laboratory study and the accessibility of the underlying neural circuitry. However, probably because of the breadth of the subject, this material has never been reviewed in a comprehensive way that presents the elements com mon to startle circuits in the different animal systems in which they occur. This book presents a diversity of approaches based on a broad back ground of animal groups ranging from the earliest nervous systems in cnidarians to the most recently evolved and advanced in mammals. The behaviors themselves are all short latency, fast motor acts, when consid ered on the time scale of the organism, and involve avoidance or evasion, although in some cases we do not yet completely understand their natural role. These behaviors occur in response to stimuli that have sudden or unexpected onset.

Expanding on the National Research Council's Guide for the Care and Use of Laboratory Animals, this book deals specifically with mammals in neuroscience and behavioral research laboratories. It offers flexible guidelines for the care of these animals, and guidance on adapting these guidelines to various situations without hindering the research process. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research offers a more in-depth treatment of concerns specific to these disciplines than any previous guide on animal care and use. It treats on such important subjects as: The important role that the researcher and veterinarian play in developing animal protocols. Methods for assessing and ensuring an animal's well-being. General animal-care elements as they apply to neuroscience and behavioral research, and common animal welfare challenges this research can pose. The use of professional judgment and careful interpretation of regulations and guidelines to develop performance standards ensuring animal well-being and high-quality research. Guidelines for the Care and Use of Mammals in Neuroscience and Behavioral Research treats the development and evaluation of animal-use protocols as a decision-making process, not just a decision. To this end, it presents the most current, in-depth information about the best practices for animal care and use, as they pertain to the intricacies of neuroscience and behavioral research.

Emotions and Affect in Human Factors and Human–Computer Interaction is a complete guide for conducting affect-related research and design projects in H/F and HCI domains. Introducing necessary concepts, methods, approaches, and applications, the book highlights how critical emotions and affect are to everyday life and interaction with cognitive artifacts. The text covers the basis of neural mechanisms of affective phenomena, as well as representative approaches to Affective Computing, Kansei Engineering, Hedonomics, and Emotional Design. The methodologies section includes affect induction techniques, measurement techniques, detection and recognition techniques, and regulation models and strategies. The application chapters discuss various H/F and HCI domains: product design, human–robot interaction, behavioral health and game design, and transportation. Engineers and designers can learn and apply psychological theories and mechanisms to account for their affect-related research and can develop their own domain-specific theory. The approach outlined in this handbook works to close the existing gap between the traditional affect research and the emerging field of affective design and affective computing. Provides a theoretical background of affective sciences Demonstrates diverse affect induction methods in actual research settings Describes sensing technologies, such as brain–computer interfaces, facial expression detection, and more Covers emotion modeling and its application to regulation processes Includes case studies and applied examples in a variety of H/F and HCI application areas Addresses emerging interdisciplinary areas including Positive Technology, Subliminal Perception, Physiological Computing, and Aesthetic Computing

This important volume brings together significant findings on the neural bases of spoken language –its processing, use, and organization, including its phylogenetic roots. Employing a potent mix of conceptual and neuroimaging-based approaches, contributors delve deeply into specialized structures of the speech system, locating sensory and cognitive mechanisms involved in listening and comprehension, grasping meanings and storing memories. The novel perspectives revise familiar models by tracing linguistic interactions within and between neural systems, homing in on the brain’s semantic network, exploring the neuroscience behind bilingualism and multilingual fluency, and even making a compelling case for a more nuanced participation of the motor system in speech. From these advances, readers have a more three-dimensional picture of the brain—its functional epicenters, its connections, and the whole—as the seat of language in both wellness and disorders. Included in the topics: · The interaction between storage and computation in morphosyntactic processing. · The role of language in structure-dependent cognition. · Multisensory integration in speech processing: neural mechanisms of cross-modal after-effect. · A neurocognitive view of the bilingual brain. · Causal modeling: methods and their application to speech and language. · A word in the hand: the gestural origins of language. Neural Mechanisms of Language presents a sophisticated mix of detail and creative approaches to understanding brain structure and function, giving neuropsychologists, cognitive neuroscientists, developmental psychologists, cognitive psychologists, and speech/language pathologists new windows onto the research shaping their respective fields.

The startle response is a reflexive behavior exhibited by animals as a reaction to threatening stimuli, such as a loud noise or sudden movement. Fish and amphibians exhibit a distinct startle behavior known as a "C-start" that allows them to swim in the opposite direction of a sensory stimulus in order to escape. This action is mediated, in part, by a pair of hindbrain neurons called M-cells. Along with other hindbrain neurons, M-cells relay information from sensory systems to the spinal cord where a motor output is produced. Here, we recorded local field potentials generated by the M-cells and neighboring neurons in the Xenopus laevis tadpole in order to understand the activity of local circuits surrounding the M-cell when it receives visual input from the optic tectum. We described 5 major components of the local field potentials that may correspond to activity from different populations of neurons. We also used pharmacological blockers to determine the influence of different types of transmission on the components. Finally, we looked at the effects of behavioral plasticity on these five components, and showed that habituation to acoustic stimuli had an effect on the mean amplitudes of them. This suggests that these networks may be involved in modulating M-cell activity in response to prolonged sensory stimulation. All together, our findings help us better understand the local circuitry involved in startle response in tadpoles, and how the activity of this circuitry is shaped by behavioral plasticity.
